Answer:
x=6 and y=4
Explanation:
Let's solve your system by elimination.
−x+3y=6; x+3y=18
−x+3y=6
x+3y=18
Add these equations to eliminate x:
6y=24
Then solve6y=24for y:
6y=24
(Divide both sides by 6)
y=4
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
−x+3y=6
Substitute 4 for y in−x+3y=6:
−x+(3)(4)=6
−x+12=6 (Simplify both sides of the equation)
−x+12+−12=6+−12 (Add -12 to both sides)
−x=−6
(Divide both sides by -1)
x=6
Answer:
x=6 and y=4
